Unformatted text preview: Regulation of Smooth Muscle Contraction:- can use similar mechanism to skeletal muscle. .. neurotransmitter release at neuromuscular junction generates action potential, which leads to rise in intracellular calcium- however, signal can be stimulatory or inhibitory for contraction- can use a variety of neurotransmitters (ACh, norepinephrine. ..), whereas skeletal muscle cells use ACh- smooth muscle cells can spontaneously depolarize in response to chemical stimuli Page5...
